Answer 1

Select all the equations that are equivalent to

0.6+15b+4=25.6

A) 15b+4=25.6

B) 15b+4=25

C) 3(0.6+15b+4)=76.8

D) 15b+25.6

E) 15b=21

ANSWER:

B, since subtracting .6 from both sides equals 15b + 4 = 25

C, since multiplying both sides of the equation by the same number, 3.

E, since subtracting 4.6 from both sides equals 15b = 21.
